Abstract

The invention discloses a hydrogen detection system. The hydrogen detection system adopts an ultrasonic resonant cavity sensor to detect the hydrogen concentration, hydrogen enters a resonant cavity, by means of the characteristic that the resonance frequency changes due to change of the sound wave conduction velocity, the hydrogen concentration is obtained, and the sensitivity is high; wireless transmission modules are arranged at a detecting terminal and a receiving terminal, remote hydrogen detection is realized, and multi-location hydrogen detection can be realized.

Description

technical field [0001] The invention relates to the detection field, in particular to a hydrogen detection system. Background technique [0002] Hydrogen is the lightest gas known in the world. It is colorless, odorless and insoluble in water. At normal temperature, the chemical properties of hydrogen are stable, but under the condition of ignition or heating, hydrogen is easy to produce with various substances. During the chemical reaction, a large amount of heat is released during the reaction, which is three times that of gasoline under the same conditions. The volume of hydrogen mixed in the air reaches 4% to 74.2% of the total volume. It will explode when heated or ignited. In the closed environment of the processing workshop, if the presence of hydrogen cannot be detected in time, once an accident occurs, the company will be given and employee personal property damage. [0003] In the existing systems for detecting hydrogen, semiconductor-type hydrogen sensors are us...
